Nonaka's model of knowledge creation and transformation, also known as the SECI model, is a theory that knowledge within an organization is created through a continuous dialogue between tacit and explicit knowledge. The model consists of four modes of knowledge conversion: Socialization, Externalization, Combination, and Internalization (SECI).

1. Socialization (Tacit to Tacit): This is the process of sharing experiences and thereby creating tacit knowledge such as shared mental models and technical skills. This often involves face-to-face communication and on-the-job training.

2. Externalization (Tacit to Explicit): This is the process of articulating tacit knowledge into explicit concepts. It's usually an iterative process where images, metaphors, and analogies are used. The creation of a concept is the key to this mode.

3. Combination (Explicit to Explicit): This is the process of systemizing concepts into a knowledge system. Individuals exchange and combine knowledge through media such as documents, meetings, and the internet.

4. Internalization (Explicit to Tacit): This is the process of embodying explicit knowledge into tacit knowledge. It is closely related to "learning by doing". When explicit knowledge is shared throughout an organization, it is internalized into individuals' tacit knowledge bases in the form of shared mental models or technical know-how.

The SECI model is a continuous and dynamic process, and it is not limited to the boundaries of an organization. It can also be applied to the creation of inter-organizational knowledge and innovation.
